TIP-ABRASION 7T3403 - Caterpillar

If the shutdown mode has been selected and the red stop lamp activates, engine shutdown may take as little as 20 seconds from the time the red stop lamp is activated. Depending on the application, special precautions should be taken to avoid personal injury. The engine can be restarted following shutdown for emergency maneuvers, if necessary.
The Engine Monitoring System is not a guarantee against catastrophic failures. Programmed delays and derate schedules are designed to minimize false alarms and provide time for the operator to stop the engine.
Programmable features monitor the following conditions:
Coolant temperature
Oil pressure
Inlet manifold air temperature
Cooling system levelCoolant Level Sensor
The system can be programmed with one of the following options:"ENABLED" - The system will monitor the input from the coolant level sensor. The system is programmed to this value when the engine is shipped by Caterpillar."DISABLED" - The system will not monitor the input from the coolant level sensor.Programmable Options and Systems Operation
If the Warning/Derate/Shutdown mode has been selected and the warning indicator activates, bring the engine to a stop whenever possible. Depending on the application, special precautions should be taken to avoid personal injury.
The engine can be programmed to the following modes:
"Warning"
"Derate"
"Shutdown""Warning"
The amber warning lamp and the red stop lamp illuminate and the warning signal is activated continuously in order to alert the operator that one or more of the engine parameters is not within normal operating range."Derate"
The amber warning lamp illuminates and the red stop lamp illuminates. After the warning, the engine will derate rpm and power. The red stop lamp will begin to flash when the derating occurs.When the engine is fully derated, the engine power is limited to 120 kW (120 hp). During a low oil pressure condition, the engine can be limited to 1350 rpm."Shutdown"
The amber warning lamp illuminates and the red stop lamp illuminates. After the warning, the engine will derate rpm and power. The engine will continue to derate rpm until a shutdown of the engine occurs. The engine can be restarted after a shutdown for use in an emergency.A shutdown of the engine may occur in as little as 20 seconds. The engine can be restarted after a shutdown for use in an emergency. However, the cause of the initial shutdown may still exist. The engine may shut down again in as little as 20 seconds.If there is a signal for coolant loss, there will be a 10 second delay in order to verify the condition. The system will derate the engine rpm for 40 seconds before the engine will shut down if the engine has been programmed to shut down.If there is a signal for low oil pressure or for coolant temperature, there will be a two second delay in order to verify the condition. The system will derate the engine rpm for 30 seconds before the engine will shut down if the engine has been programmed to shutdown.For more information or assistance for repairs, consult your Caterpillar dealer.Note: The Customer Specified Parameters may be secured by customer
